Random noise refers to unpredictable fluctuations or disturbances in data or signals that do not follow a discernible pattern, often obscuring the underlying information or signal. It is a fundamental concept in various fields, including statistics, signal processing, and information theory, where distinguishing between noise and meaningful data is crucial.

Signal processing involves the analysis, manipulation, and synthesis of signals such as sound, images, and scientific measurements to improve transmission, storage, and quality. It is fundamental in various applications, including telecommunications, audio engineering, and biomedical engineering, where it enhances signal clarity and extracts useful information.

Information theory is a mathematical framework for quantifying information, primarily focusing on data compression and transmission efficiency. It introduces fundamental concepts such as entropy, which measures the uncertainty in a set of outcomes, and channel capacity, which defines the maximum rate of reliable communication over a noisy channel.
